The assembly language for bar() is (gdb) disass bar Dump of assembler code for function bar: 0x00000000004004cd 0x00000000004004ce 0x00000000004004d1 0x00000000004004d4 : mov 0x00000000004004ac(+15); mov 0x00000000004004df :retq push mov mov mov %rbp %rsp, %rbp %edi,-0x14(%rbp) -0x14(%rbp),%eax %eax,%eax %eax,-8x4(%rbp) -0x4(%rbp),%eax pop %rbp End of assembler dump Give a 1-2 sentence description of the purpose of each instruction.
